Class Method Details

.optionsObject

Set options for running the benchmarks. :format => [:human, :raw]

:human format narrows precision and scales results for readability
:raw format displays 6 places of precision and exact iteration counts

Instance Method Details

#ips(*args) {|job| ... } ⇒ Report

Measure code in block, each code's benchmarked result will display in iteration per second with standard deviation in given time.

Yields:

  • (job)
